“…These plots per treatments were replicated three times, which were comprised of one to three rows in family subplots. No thinning was applied in the site although 24 trees were sampled to examine wood-property variations in 2013 (Prasetyo et al, 2016).…”

“…Although there are few reports estimating the genetic variation and heritability for Z. serrata, heritability of growth traits in the species were generally ranged from 0.2 to 0.4 (Endo et al, 1998;Takeuchi et al, 1999;Mori et al, 2004;Yoshino et al, 2006;Kawai et al, 2011;Prasetyo et al, 2015Prasetyo et al, , 2016Prasetyo et al, , 2017. Takeuchi et al (1999) examined the genetic variations in growth traits in 2-year-old Z. serrata families grown in three different regions of Japan (Kanto, Kansai, and Kyushu).…”

Variance components of tree height (HT) and stem diameter at 1.3 m above the ground (DBH) were investigated for the eight open-pollinated families of Zelkova serrata (Thumb.) Makino planted with three different initial planting spacings in a progeny test site, Chiba, Japan. Parent–offspring correlations were also evaluated by using these families and their mother trees. The smallest values of HT and DBH were observed in the narrowest initial planting spacing (1.10 x 1.10 m) compared to those in medium (1.30 x 1.36 m) and wide (2.00 x 1.80 m) spacings, suggesting that adverse effects of competition with neighboring trees occurred on both height and radial growth. Similar to HT and DBH, the initial planting spacings also affected the genetic parameter estimates: the ratio of family variance component to total phenotypic variance showed the highest value in narrow initial planting spacing for both HT and DBH. Thus, family variance component might include competition effects, leading to biased genetic parameter estimates. In contrast, parent–offspring correlation coefficients showed the highest value in wide initial planting spacing where competition effect might be smaller. Therefore, the growth traits of Z. serrata might be inherited from the parent to the offspring when competition effect was small.
